The optimized management of waste releases is a priority for Enel, which aims at the decrease of waste production, the increase of waste recovery (also by better sorting), the qualification of suppliers of waste disposal services and the use of information systems for waste traceability.
Waste management in Italy has achieved excellent results. Thanks to consistent improvements compared to previous years,
Enel was able to almost totally recover its waste.
Through awareness-raising activities aimed to this end, the Group also wishes to spread this operational excellence abroad. Considering Enel's international operational context, about one third of the total waste produced is currently recovered.
Special waste is managed by Enel in accordance with national laws in force in the different countries of operation.
According to EU legislation, special waste includes:
Non-hazardous special waste
These include mainly light and heavy coal ashes and gypsum from desulphurization. A smaller part consists of machinery and equipment, materials removed from the grids of intake structures of hydroelectric plants and part of alluvial sediments removed by mechanical means from emptied reservoirs. The category also includes debris from geothermal drillings, sludges from water treatment, packaging and other waste which is not included in the abovementioned categories.
Hazardous special waste
These include a greater share of fly ash from oil fuel, equipment such as transformers and capacitors containing PCBs and their parts and waste materials contaminated by geothermal fluids.
Also, used lubricating oils, exhausted batteries, materials containing asbestos, sludge produced when geothermal steam is condensed and other liquid and solid waste.
